Differences between a channel and a receptor?
A channel is a pathway through which ions or molecules can flow across a cell membrane, facilitating cellular communication. On the other hand, a receptor is a protein that binds to specific signaling molecules such as hormones or neurotransmitters, triggering a cellular response. Channels regulate the movement of substances, while receptors initiate signaling cascades within the cell.
What channel can help move things across the membrane?
Ion channels facilitate the movement of ions across the membrane. These protein channels create a passageway for specific ions to move down their concentration gradient, facilitating processes such as nerve signaling and muscle contractions.
Ion channel gates close the pore of some ions channels in response to what?
Ion channel gates close in response to changes in membrane potential, ligand binding, or mechanical stimuli. These triggers help regulate the flow of ions through the channel, allowing for precise control of neural signaling and other essential biological processes.
Synaptic signaling between adjacent neurons is like hormone signaling in which way?
Synaptic signaling between adjacent neurons is similar to hormone signaling in that both involve chemical messengers (neurotransmitters in synapses, hormones in endocrine system) transmitting signals between cells. However, synaptic signaling is typically faster and more localized, while hormone signaling is slower and can have more widespread effects on distant target cells.
What ion channel is a transport protein that?
An ion channel is a transport protein that allows specific ions to pass through the cell membrane. It is a key component in maintaining the electrical potential of a cell and is crucial for various physiological processes, including nerve signaling and muscle contraction.
What type of signaling transmits call setup on the same channel as a voice signal?
In-Band Signaling (IBS)
What is In- channel signaling?
In-channel signaling is also often referred to as in-band signaling. See http://en.wikipedia.org/wiki/Signalling_(telecommunications)#In-Band_versus_Out-Of-Band and http://en.wikipedia.org/wiki/In-band_signaling.The signaling used to establish and tear down a phone call was located in the same physical communication channel used to carry the call (i.e voice, fax or modem) traffic, and used DTMF tones. Examples are CCITT Signaling Systems 1-5 R1 & R2. Most books on SS7 should talk briefly about this.SS6 & SS7 moved to take the signaling out-of band, and to establish a common channel for all signaling in digital packet-based format (non-tone based) allowing one signaling channel to control a large number of "voice" circuits.
Which PTSN connection usually uses common channel signaling and Signaling System 7 technology?
A connection between two exchanges connection
What is signal?
In telephony, signaling is the exchange of information between involved points in the network that sets up, controls, and terminates each telephone call. In in-band signaling , the signaling is on the same channel as the telephone call. In out-of-band signaling , signaling is on separate channels dedicated for the purpose.
What are the disadvantages of common channel signaling?
•CCS links can be a single point of failure •No inherent testing of speech path by call setup signaling •CCS response time is critical
What is the difference between in channel and common channel signaling?
One signaling path needed per trunk groupFaster and simpler to transfer information between control processorsNo possibility of interference with speech pathSignaling can't be accessed by customer.Value-added services of a signaling control pointShared processing for small officesAllows centralized decision making (flow mgmt)Permits Advanced Intelligent Network (AIN) services
Binding of a signaling molecule to which type of receptor leads directly to a change in distribution of ions on opposite sides of the membrane?
Ion channel receptors. These receptors allow specific ions to flow through a channel when activated by a signaling molecule, resulting in a change in ion distribution across the membrane and altering the membrane potential.
When was history.com made?
History.com is the website that is associated with the History channel that is available on TV. The channel was founded on January 1st, 1995.
What is a telecommunications network protocol?
is the set of standard rules for data representation, signaling, authentication and error detection required to send information over a communications channel

How can you provide for signaling when using a 24B T1 primary rate interface configuration?
By using a D channel on another PRI across the same user network interface
What is mean by d and b channels in a pri line?
D (Delta channel) carries control and signaling traffic. B (Bearer channel) carries the actual data and/or voice traffic. A U.S. PRI consists of 23 Bearer channels and 1 Delta channel for a total of 24 channels per PRI.
